Definitions

  • This invention relates to a vang assembly for controlling the boom of a sailboat.
  • a vang is an adjustable device fitted to the underside of a boom to control the raising or lowering of the boom.
  • Vangs typology can be divided into two basic types: soft vangs and mechanical vangs.
  • the most widely used vangs, in particular for smaller boat are soft vangs.
  • a typical soft vang includes a multiple purchase block and tackle system including two or more blocks or pulleys attached to the boom, and a single line having one end secured to one of the pulley systems, with the line having a free end which is pulled out and released manually by the sailor.
  • a soft vang increases sail efficiency by pulling down on the boom in medium or heavy air, thereby increasing the tension in the leech and reducing the spill of wind.
  • the tackle rigging When the tackle rigging is tightened, it applies a downward force on the boom and compresses the spring within the telescoping aluminum tubes. As the rigging is loosened, the spring within the telescoping aluminum tubes extends, thus providing support for the boom.
  • the spring cpm prises a steel coil; however, compressed-gas cylinder springs are also used.
  • a second variety of mechanical vangs are screwdriven or "rotary" vangs.
  • a large turnbuckle is lengthened or shortened by turning a wheel or a pair of handles in the middle of the turnbuckle.
  • screw-driven vangs have the serious disadvantage of being difficult and slow to adjust because of their heavy nature.
  • a third variety of mechanical vang are hydraulic vangs. Hydraulic vangs typically consist of a cylinder filled with hydraulic oil and a piston. A hydraulic pump controlled from the cockpit actuates the piston inward or outward to control the height of the boom.
  • the fourth variety of mechanical vang are flexible column actuated vangs.
  • This type of vang is actuaded with a device that is capable of being moved between a contracted position and an extended position.
  • the adjustment mechanism When the adjustment mechanism is moved to a contracted position, the column is forced to bow arcuately to an arched position and the boom is forced in a downward direction.
  • the adjustment mechanism When the adjustment mechanism is released to extended position, the arcuately bowed column straightens and exerts forces pushing the boom upwardly.
  • the present invention comprises a vang assembly for manipulating a sailboat boom which is hingendly connected to the lower portion of a sailboat mast.
  • the vang assembly includes a rigid and unextensible vang (strut) connected both to the mast and to the boom.
  • the first end portion is hingendly attached to the lower portion of the mast below the boom, and the second end portion is hingedly attached to a traveller sliding on track fixed to the boom at a location spaced outwardly from the lower portion of the mast. Traveller fore and aft movements are controlled by block and tackle system.
  • Traveller sliding allows to control boom vertical position.
  • a simpler configuration of the system includes traveller forward movement control only and therefore the upward boom forcing control. In this case the downward boom forcing control is made by a block and tackle traditional vang.
  • the boom vang system of the invention completely elimanates the problems above referred to the other mechanical system, in particular avoids any complex mechanical part, such as spring, telescopic pipe, hydraulic pump etc. and therefore avoids necessity of maintenance.
  • Boom control is made by a track and traveller system that is a well known extremely reliable and absolutely durable system.
  • the rigid strut made by alluminium, composites or other materials is a strong, light and durable (no maintenance) component of the system.
  • Up and down boom control can be easily performed also without tension to the pull down takle rigging in particular in light wind or when docked. All the mainsail operation become very easy.
  • FIG. 1 is a side elevational view illustrating a first embodiment of the mechanical vang of the present invention disposed between the mast and the boom of a sailboat.
  • FIG. 2 is a sectional side plan view of the strut (20) of FIG.1 showing inside pulling down rigging.
  • FIG: 3 is a sectional side plan view of the strut (20) of FIG.1 showing inside hold up rigging.
  • FIG. 4 is a plan of strut 20, with an inside view, along the line 4-4 of FIG. 1.
  • FIG. 5 is a sectional view along the line 5-5 of FIG. 4
  • FIG. 6 is a side view of an additional embodiment of the mechanical vang of the present invention.
  • FIG. 7 is a side view of an additional embodiment of the mechanical vang of the present invention.
  • FIG. 1 A vang assembly, generally designated 10, of the present invention is shown in FIG. 1 positioned between a lower portion of a mast 12 and a boom 16 of a sailboat.
  • the vang assembly broadly includes a rigid strut, generally designated 20, hingendly connected to the mast 12 with a tang 22 via hinge 24 and hingendly connected to a traveller 26 via hinge 28.

Abstract

Ensemble hale-bas servant à manipuler la bôme d'un voilier et accouplé par une articulation à la partie inférieure du mât (12). Cet ensemble hale-bas comprend un hale-bas (entretoise) (20) rigide et non extensible accouplé à la fois au mât (12) et à la bôme. La première partie d'extrémité est fixée articulée à la partie inférieure du mât en dessous de la bôme et la deuxième partie d'extrémité est fixée de façon articulée à une barre d'écoute (26) se déplaçant sur un rail (30) fixé à la bôme au niveau d'un emplacement s'éloignant vers l'extérieur depuis la partie inférieure du mât. Les déplacements avant et arrière de la barre d'écoute sont contrôlés par un système de moufle. Le glissement de la barre d'écoute permet de contrôler la position verticale de la bôme. Quand la barre d'écoute est tirée vers l'avant (en direction du mât), la bôme est soulevée par le hale-bas rigide servant alors d'entretoise et quand la barre d'écoute est tirée vers l'arrière (en face du mât), la bôme est descendue par le hale-bas rigide servant de tirant.
